erated by the combining of acid and alkaline water.

The principal object of my invention is to provide a neat and efficient apparatus which may be disposed on a wall surface with elements thereof to be in such proximity to the floor as to be readily accessible when it :is desired to bring the extinguisher into use.

Other objects of my invention are to provide an extinguisher of the character described including a revolubly mounted drum-like container wherein the extinguishing fluid is generated, which serves as the reel for supporting the hose in connection therewith, and whereby, by a minimum effort, the container may be actuated to ef" feet the required chemical combination to render the apparatus active for extinguishing purposes. By this construction, the apparatus may be brought into use by persons other than adults, since the container itself is not bodily transported but merely revolved about stationary bearings.

Other objects of my invention will appear in the following detailed description, in connection with the accompanying drawing forming a part of this specification, and in which d ra wi ng Figure 1 is a front elevation of the apparatus embodying my invention. Fig. is a side elevation of the saine. Fig. 3 is a view partly in elevation and partly in section showing a detail of apparatus. Fig. t is a view in central longitudinal section through the container. Fig. 5 is a detailed sectional view showing the acid receptacle in a nor-.

inal position. Fig. .6 is a view similar to Fig. 5 showing the position of the acid receptacle for effecting a chemical combination. Fig. 7 is a combined view, in elevation, showing an acid receptacle and device for handling the same.

Similar characters refer to similar parts throughout the several views.

I prefer to carry the elements of the apparatus embodying .my invention, upon a plaque-like support 1 so that, as an article of manufacture, it may be assembled and in readiness to be secured to the wall of a building. Secured to support 1 are brackets 2 having bearings 3 for the reception of trunnions at of a drum-like container 5. The brackets 2 are so disposed as to mount the container with its axis of rotation substantially horizontal.

Referring more particularly to container 5, it has a peripheral opening 6, adapted to be closed against egress of fluid by a cap 7. lVithin the container I provide a frame 8, preferably formed of a plurality of uprights 9, and a base 10, the ends of the former being secured to the internal periphery of the container adjacent the opening 6, the frame normally depending about the said opening.

The frame 8 is adapted to receive a cylindrical receptacle 11 for acid, between said uprights 9 and has provided segmental flanges 12 disposed circumferentially about its exterior and preferably adjacent to its bottom. These flanges cooperate with abutinents 13, carried by frame 8, to prevent the receptacle from dropping, due to force of gravity, when the container is revolved. I prefer to provide eyes lt laterally of container 11, to receive the hooked ends of an element 15, clearly shown in Fig. 7 of drawing, whereby the receptacle may be placed in the frame 8, after having removed cap 7. lVhcn disposing receptacle ll in up erative relation to the other elements of the apparatus, the former is let down by aid of element 15, and turned slightly so that the flanges .12 are disposed in under abutn'ient 13. A lid 16 is provided for receptacle 11, however, the latter is so held, when the container 5 is revolved, that this lid may drop freely from the receptacle and permit egress i of the acid therein, into the container 5 to intermix with the alkaline water in the latter, as clearly shown in Fig. (3 of the draw ing.

The drum-like container 5 receives coils of hose 17, made of any suitable flexible material, one end of which is provided with a valved nozzle 18, and the other end being conductively connected, as by pipe 19, with the interior of the container. I may find it desirableto provide flanges 20 circumferentially about the container to confine the coils of hose about a predetermined portion of the periphery thereof.

Within the container 5 I provide a tubular element 21. one end of which is. provided with weighted strainer 22, the other end be ing conductively connected with pipe 19 by a flexible member 23. By this'construction, the element 21, with its trainer 22, is. pendently supported from said pipe 19 and adapted, by the influence of the force of gravity, to dispose the strainer 22 lowermost as clearly shown in Fig. 1'of the drawing. This disposes the intake of hose 17, lowermost in container 5, regardless of its position upon the pivotal support.

his to be understood that the intermixing of acid in receptacle 11 with the alkaline water in container 5 produces a force within the container which feeds the fire extinguishing fluid through the hose17. In order to prevent collapsing of member 23 the force, the same maybe reinforced by wires 24, within the material of this member or disposed within the same.

'When the apparatus is not in use the end of hose 17, provided with nozzle 18 is pendently disposed tangentially from container 5 to be in such proximity to the floor adjacent the wall upon whichthe apparatus is sup ported, asto enable a personto grasp such end and unwindthe hose from the container. This, of course, welghts the container eccentrically and would normally tend to rotate the" same, however, I provide a normal drag upon the container, which may be constructed as shown in'Figs. 1 and 2' ofthe drawing, to compensate for this. This drag means may comprise a ratchet wheel 25'rigid with fore described, with receptacle 11 disposed with its opening uppermost as shown in Figs. 4 and 5, and with aportion of hose 17 depending tangentially from the container.

l/Vhen it is desired touse the apparatus, the.

depending portion of the hose is grasped and drawn toward the burning material, which action revolves the, container 5 and disposes the receptacle 11 to permitinten,

mixing of acid and alkaline water providing for the desired pressure within the contalner to force-fluid through the hose. The egressaxis, a receptacle carried'by and disposed within said container and positioned to freely emit its contents when said container 1 is rotated, a hose in conducting communication with the interlor'of said conta ner and wound. about the periphery thereof with'its nozzled end pendent to one side thereof, and means for coimteracting the weight of said pendent portion of said hose but yieldable when a force is applied to the said pendent to unwind the same.

portion of said hose container 5, and a pawl 26,'for cooperation 1 from said container.

therewith, carried by one of the brackets 2;

The operation of the apparatus is as'fol- 1 lows: The container is normally retained against rotation by the drag means hereinbe- EDWVARD F. MEARA. l/Vitnesses:
